When issues arise in New Zealand we often look for an answer that is far removed from the actual cause of the problem.
Emissions Trading is a gigantic shambles - not caused by climate change because we have had climate change for millions of years - but caused, and then made worse, by politicians. Cause of problem = politicians.
Legal Aid Review
As someone who has some links to the law profession, the Bazley report into legal aid is unsurprising. The problems in Manukau have been well known for years and no one in the legal profession had the guts to do anything about it. But when you create a system that allows it to be milked like a cow; and when standards at law schools slide on the back of affirmative action policies (put in by politicians), bums on seats attitudes (put in by politicians) and examiners failure to fail students (tacitly allowed by politicians so that the bums on seats can prevail), what you get is poorly educated lawyers on a gravy train. Cause of problem = politicians.
Supreme Court judgment recall
What can one say on this story apart from this: we had a perfectly functional appellate court process that was not open to the closeness that New Zealand society inexorably provides. That was called the Privy Council. Some politicians (Clark et al) decided we should scrap that and leave ourselves open to the biases and allegations of tainting that only a very small country at the bottom of the World can. Cause of problem = politicians.
When you look behind these issues they are all ultimately caused by politicians. The legal aid problem isn't the result of bad lawyers, it's the result of bad politicians. Emissions Trading isn't the result of climate change, it's the result of poor politicians. And the Supreme Court story isn't caused by the failure to disclose bias, it was caused by the removal of the Privy Council - a political decision. The best reason for retaining the Privy Council was because we are such a small country that the six degrees of separation paradigm drops back to about two degrees in this country. Everyone knows everyone who knows everyone.
